python - icontains and SQL Security -


i have web app allows users enter search query retrieve models match search criteria. here methods: 

@staticmethod def searchbody(query):     '''     return entries body text contains query.     '''     return entry.objects.get(text__icontains=query)  @staticmethod def searchtitle(query):     '''     return entries title text contains query.     '''     return entry.objects.get(title__icontains=query)  @staticmethod def searchauthor(query):     '''     return entries author text contains query.     '''     return entry.objects.get(author.icontains=query)

my question simply: secure stands? in other words, incontains perform necessary string escaping operations person can't inject sql or python code query launch attack?

yes, django orm protects against sql injection.

of course can never entirely sure there no security vulnerability in application. nevertheless, orm component responsible protecting against sql injection, should assume it's safe , keep django install date!

on unrelated note, there typo in entry.objects.get(author.icontains=query).

also, using .get going throw lot of errors here (whenever object doesn't exist, or more 1 exist). doesn't docstring says either.

you want using .filter instead.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
